Several generations later, in 1343, Sir Robert Bertram was given permission to turn his manor house into a castle, including an impressive gatehouse.

The gate tower and fragments of curtain wall are medieval, a good deal of which still survive to this day.

Shrewsbury's agents visited Bothal, and described the house as 'a castle battled, and not unlike to Nether Haddon where Master John Manners doth dwell.

'[4] In 1591 the estate passed to the Cavendish-Bentinck family (Dukes of Portland), through the marriage of Catherine, Countess of Ogle to Sir Charles Cavendish of Welbeck.

[1] The building is used as a private residence of the Cavendish-Bentinck family and also houses the Welbeck Estate Office.
